🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by binding to glucocorticoid receptors in the cytoplasm of cells. This binding causes the receptor to move into the nucleus, where it alters the transcription of many genes. The result is a decrease in the production of inflammatory mediators such as prostaglandins, leukotrienes, and cytokines. It also suppresses the immune system by reducing the activity of white blood cells. These actions lead to reduced inflammation, allergic responses, and immune reactions.
